PART $3.$ Summing Amplifier

a$)$ Calculate the voltage gain of the noninverting amplifier in fig. $7\mathrm{.}8$ with inputs of $V_1=V_2=1V,$ peak at $f=10kHz.$ For $R_0=100k,R_1=100k,$ and $R_2=22k.$

$V_o($ calculated from $eq.7\mathrm{.}4)=$

b$)$ Construct the circuit of fig$\mathrm{.}7\mathrm{.}8.$ Apply an input of $V_1=V_2=1V,$ peak at $f=10kHz.$ Using an oscilloscope, measure and record the output voltage

$V_0($ measured $)=$

Compare the output voltage calculated in Part $4($a$)$ with that measured in Part $4($b$)$

c$)$ Replace $R_2$ with a $100k$ resistor. Repeat Parts $4($a$)$ and $4($b$)$

$V_O($ calculated $)=$

$V_o($ measured $)=$
